A man and a forklift truck lift equal masses 10 feet vertically. Of the following statements, the correct one is: insufficient information is given to compare the work done by the man and the forklift the forklift does more work than the man they do the same amount of work the man does more work than the forklift

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

answer is slate

hope this
